IMPROVEMENT 1N vAPoEIzINe AND BURNING eAsoLINE Een HEATING ANN nLuurNmNe.,

Be it known that I, HENnY Gil-BERT, of the city of Philadelphia, Stato of Pennsylvania, have invented an' Improvement in Veporizing and Burning Gasoline for Heating and `Illuminating Purposes, .the nature of' w'heh consists in overcoming the deieets ot' the precoding, patented by William Besche, August 14, .1866, No. 57,245

These defects n're, iirst, the tting oi' partei' the burner and part of thebody 4of Jhe lamp with nire gauze, which, being top good a conductorof heutiorthis purpose, euusesve,ry often, an explosive spitting of the 11eme; secondfthe fitting of the vent of theburner with asbestos, which, possessing too little porosity, eholies up the liquid ands-ilse causes the lomp to ,refuse taking iire before the burner is for along time exposed to a.

iame end considerably heated;l third, theabsenee of the 'possibility of regulating the ame; consequently, stronger ythe lamp burns, stronger the heet, and stronger the evaporation, and stronger the Home; und so the lamp will sometimes go on burning with a continually increasing intensity before it beeomes regular, and then burnswith a ame largerthan is sometimes desired. v

The first objection I overoome'by omitting the wire gauze'in the lump, as well as in' the burner, and filling it all Awith saw-dust, pr substituting for this, inthe burner, u. well-fitting piece of eharoal, retten, cotton, wool, hemp, ax, jute, orotlrer equivalent porous material. The second objection I ovoreomeby discarding tho asbestos, not only as useless, but es decidedly injurious.v The third objection`I overcome by adding to the burner a stop-cock or other similar` oontrivence, in order to regulate theA supply of gasoline vapors. V

I'n order to enable others skillful 'in these matters to use my improvement, I give here a. full description in illustration of the annexed drawings. o

`a 6 e :i represent the body of the gasoline safety-lamp in its present mest improved. style,"but which may have any desiredshupe. It is entirely filled with saw-dust. g 7L is-the burner, provided at its lower part with a regulating stop-cock, e j". The burner is iilled with sow-dust,'eotton,charcoal, or unyfof the mentioned materials. As the filling of the lamp abovevis very objetionable, :in opening below isy provided for, closed with a screw-top, with or-without a valve-and represented by m.

Inside of the opening is a piece of wire gauze, p g, serving to prevent-the sawdust from felling out when the screw is removed for the purpose of lli'ng the lamp, Y Figure 2 represents a lamp where the metallic burner is entirely omitted and its place supplied by e. little cup, 128,'of tine wire geuze,"throu`gl1 which thevupors from thev wick escape and burn. In the openings of cans, tanks, barrels, etc., I-use afbundle of metullic'wire in place of the r,oll 'edup wire gauze, as giving a. better passage to the liquid, and increased safety. i

What I elini as my invention,iand wish to secure by Letters Potent, is

1 The serew-stop\vith or without valve at the bottom, intendedto iill the reservoir orgvessel with the combustible iiuid from below. A i i 4 i 2. The stopfeoek or its equivalent in the burner, serving to regulate the exit of ,gasoline vapors, and consequently the size of the-dame. i

3. The filling of ythe lamp or burner, or both, with saw-dust, chareoul, powdered or otherwise, bone-dust,

cotton, iiaix, hemp, wool, rattan; jute, or, other similar porous substance.

l4. The modification of sztid lamp by omitting the metallic burner entirely und burning it by means of a wick, covered or not eovcred byte. eup'of wire gauzeor by burning it without any wickby means ofthe metallic burner. i y 'i i i 5. The use ot a. bundle of fine metallic wire in tho openings and stop-cocks of cans, bottles, tanks, barrels, or other reservoirs for fluid'4 combustible substancemgving a. better ingress and egress to the liquid material than is the case withwirefgauze, and gte-ting es un improved safety arrangement inpreventing any tiameto comnl'nicate to the interior and causeexplosions. i

In' testimony whereof I have signed my name to thisspeciicetion inthe presence of twosubscribing witnesses.
